Study confirms link between maternal diabetes and autism
WASHINGTON: A new American study has shown that diabetes during pregnancy is associated with an increased risk of brain and nervous system problems in children, particularly autism.
The study, published in The Lancet Diabetes & Endocrinology journal, showed that diabetes diagnosed before pregnancy increases the risk of one or more neurodevelopmental disorders by 39 per cent compared to gestational diabetes, which begins during pregnancy and often resolves afterward.
According to the researchers, the findings highlight the importance of medical support for women at risk of diabetes and continued monitoring of their children.
Children born to mothers with gestational diabetes have a 25 per cent increased risk of autism, a 30 per cent increased risk of attention deficit hyperactivity disorder, a 32 per cent increased risk of intellectual disability, a 20 per cent increased risk of communication problems, a 17 per cent increased risk of motor problems, and a 16 per cent increased risk of learning disorders compared to children whose mothers did not have gestational diabetes.
For her part, Dr Magdalena Janicka of New York University Grossman School of Medicine said: 'Such analysis allows us to compare groups more precisely, but they do not bring us closer to understanding the causes or underlying mechanisms'.
A large 'meta-analysis' like this one allows for analyses of subgroups, such as mothers with pre-existing vs gestational diabetes, or children with autism vs those with ADHD or movement disorders, but it cannot prove cause and effect, Janecka said.
"Meta-analyses allow us to compare groups more precisely. At the same time, they are not bringing us any closer to understanding the causes or the underlying mechanisms.'
The study comes as Trump administration health officials have called for further research into whether vaccines are a cause of autism, a claim long championed by new Health Secretary Robert F Kennedy Jr. that has been debunked by established science. — Reuters

Trump withdraws NASA nomination of Musk associate
Washington, D.C., US – President Donald Trump has withdrawn the NASA nomination of Jared Isaacman, a billionaire tech entrepreneur and private astronaut who has commanded and funded two SpaceX missions to Earth orbit, the White House has confirmed. Isaacman's removal comes just days after Elon Musk's official departure from the White House, where the SpaceX CEO was serving in the role of a 'special government employee' leading the Department of Government Efficiency (DOGE). Trump said he would announce a new candidate soon. 'After a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA,' the US president posted on his Truth Social platform on Saturday. 'I will soon announce a new nominee who will be mission aligned and put America first in space,' he said. The move came just days before the Senate was scheduled to vote on his confirmation, where he was widely expected to be approved. According to The New York Times , President Donald Trump had concerns about Isaacman's political loyalty. The news outlet reported that Trump was informed of Isaacman's donations to Democrats in the past two campaign cycles. 'The Administrator of NASA will help lead humanity into space and execute President Trump's bold mission of planting the American flag on the planet Mars,' White House Assistant Press Secretary Liz Huston told Fox News Digital on Saturday. Isaacman, 42, said he was 'incredibly grateful' to Trump and 'all those who supported me throughout this journey'. 'I have gained a much deeper appreciation for the complexities of government and the weight our political leaders carry,' he posted on X. 'It may not always be obvious through the discourse and turbulence, but there are many competent, dedicated people who love this country and care deeply about the mission.' Meanwhile, Musk also took to X to post: 'It is rare to find someone so competent and good-hearted.' Trump announced his choice of Jared Isaacman in December, before the president's inauguration, and the nominee seemed poised to be confirmed by the US Congress. A US Congress Committee on Commerce, Science, and Transportation voted this April to advance his nomination to the full Senate for confirmation. Issacman had, in September last year, become the first private astronaut to perform a spacewalk after launching on a SpaceX rocket. Meanwhile, on May 30, the White House released its NASA budget request for the 2026 fiscal year. The documents propose a US$6bn budget cut for the agency, from US$24.8bn to US$18.8bn, with funding for NASA's science programmes slashed by 47 per cent. It indicated that NASA's workforce would be reduced by nearly a third, for example, and dozens of the agency's science missions – including the Juno Jupiter orbiter, New Horizons Pluto probe and a number of other spacecraft that are currently gathering data in deep space – would be cancelled.

HEAT WAVE HAZARDS
Maureen Salamon With June's arrival, summer heat waves can't be far behind. They're happening more often than ever: according to the Environmental Protection Agency, the average American city experiences six heat waves — prolonged periods of unusually high temperatures — each summer, three times as many as in the 1960s. Beyond comfort, paying attention to rising mercury levels is vital to our health for a key reason. Certain medications can leave us more vulnerable to heat-related effects or the sun's rays and higher temperatures may render medicines less effective. Most people don't consider that the weather can amplify drug side effects. "But they should, because it can be dangerous if you don't take the right precautions," says Magie Pham, a primary care pharmacist at Harvard-affiliated Brigham and Women's Hospital. Tens of millions of Americans take drugs that can change the way they tolerate intense heat and sunshine. Over all, about three-quarters of Americans ages 50 to 64 take prescription drugs, a proportion that climbs to nine in 10 people at 65 and older. The situation is similar with over-the-counter drugs, which adults 65 and up use more than any other age group. There's no magic number the temperature must reach before this issue becomes relevant. It's relative, Pham says, since people who live in warmer climates year-round typically have different thresholds for how heat affects them compared with those who live in four-season climes. "Every person tolerates heat differently," she says. Research indicates that people become increasingly vulnerable to heat as they age, since their ability to sweat efficiently and circulate blood to the skin — two key ways the body cools itself — decreases over the decades. (See "Know the signs of heat stress.") Older women are also more physiologically vulnerable to high heat and humidity compared with men of the same age, according to a study published online on August 26, 2024, by the American Journal of Physiology–Regulatory, Integrative and Comparative Physiology. MEDICATIONS TO WATCH Known as "water pills," diuretics make us urinate more, removing excess fluids from the body. But these drugs, which are prescribed to manage conditions such as high blood pressure, heart failure, kidney disorders, or glaucoma, can make it more likely you will become dehydrated quickly in extreme heat. They can also lead to imbalances in levels of electrolytes — minerals essential to various bodily functions — which make it harder for the body to regulate its temperature. "We see many people who've been fine for a long time on diuretics, but then they go somewhere a lot warmer than they're used to and end up becoming severely dehydrated," Pham says. "It's probably the medication I'm most worried about." Other blood pressure drugs. These widely prescribed medications, which include ACE inhibitors, beta blockers and calcium-channel blockers, raise the odds of fainting and falling if they drive blood pressure too low. "If someone is already dehydrated, that can also lower their blood pressure, causing them to faint or fall," Pham says. "It's more of a domino effect from being out in the sun." Doxycycline. This antibiotic is just one example of the many drugs that cause photosensitivity, "meaning you're more likely to get sunburned," she says. "The safest way to avoid that is to make sure you wear sunscreen any time you're going to be outside — even on a cloudy day, because you can still get sunburn." Some antidepressants. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) can make you sweat more and impair your body's ability to regulate temperature, hindering your ability to stay cool. "You don't realise how warm you're getting when you're taking these medications," Pham says. "It's important to be hydrated and wear sun-protective clothing, such as a hat, as well as stay in the shade. These approaches can make a real difference in keeping your temperature down." Thyroid hormone. One of the most frequently prescribed medications in the United States, thyroid hormone — usually in the form of levothyroxine (Synthroid, Tirosint, Unithroid) — treats hypothyroidism (an underactive thyroid gland), a condition far more common among women than men. Like other medications above, thyroid drugs can impair the body's temperature regulation, making people sweat too much and increasing the chance of dehydration. Adding to the risk, older people are less likely to realise thirst and sense the degree of heat. Some over-the-counter antihistamines. Used for allergies and also as a sleep aid, diphenhydramine (Benadryl) and doxylamine (Unisom) may be helpful during the pollen explosion common to hot weather. But like other medicines, they can also hinder sweating and impair core temperature control. Additionally, they raise your risk of sunburn. Most medication labels direct us to keep the substance in a cool, dry place. That's because elevated temperatures can damage drugs in ways both known and unknown. Insulin, for example, which requires refrigeration, becomes unusable in the heat; inhalers, which are pressurised, can explode; and EpiPens, used to counter extreme allergic reactions, can malfunction. But scientific studies don't typically examine the effectiveness of drugs beyond room temperature, Pham notes. "If it's 80° or 85°, we have no idea how effective those medications are," she says. "But it makes sense to believe that they're not going to work as well as if they're kept at a more moderate temperature." Plan ahead to avoid exposing your medications to unstable temperatures while you're travelling. On road trips, place medicines in a cooler, not your car's glove box, which can get too hot even if you have the air conditioning on. For plane flights, stash your medications in your carry-on bag, since checked luggage can get lost or delayed and temperatures in a plane's cargo hold can be variable. "Unfortunately, the temperatures where luggage is stored can be too hot or cold," Pham says. Also, check with your prescribing doctor or pharmacist about how long medications requiring refrigeration can be safely kept at room temperature. And before you fly, Pham suggests calling the Transportation Security Administration toll-free at 866-289-9673 for guidance about medications you'll be carrying, so no snafus arise as you pass through airport security checkpoints. "Your doctor can also provide you with a travel letter to present to TSA representatives so you have no issues," she says. — The New York Times SIGNS OF HEAT STRESS - hot, dry skin or profuse sweating - confusion - throbbing headache - loss of coordination - rapid heart rate - extreme weakness - fast, shallow breathing - nausea and vomiting - loss of consciousness - Heat-related drug damage

Joe Biden diagnosed with aggressive prostate cancer
Washington D C, US – Former US President Joe Biden has been diagnosed with an aggressive form of prostate cancer, his office confirmed on Sunday. The 82-year-old Democrat, who served as President from 2021 to 2025, is said to be reviewing treatment options with his family. The cancer has been given a Gleason score of nine, indicating it is an advanced case that has metastasised to the bone. However, according to the statement, the disease is hormone-sensitive, which opens the door to effective management strategies. Biden, who abruptly withdrew from his re-election campaign in July 2024 amid growing concerns about his age and health, now faces a new personal challenge. His son, Beau Biden, died of brain cancer in 2015 – a tragedy that deeply affected the former president. A long political career Biden's political life began in 1972 when he was elected senator for the state of Delaware. He served six terms in the Senate before becoming Vice President under Barack Obama from 2009 to 2017. In 2020, he defeated incumbent Donald Trump to become the oldest president in American history at the time. However, facing mounting scrutiny over his mental and physical fitness – particularly after a shaky televised debate in 2024 – he ended his bid for a second term. His then-Vice President, Kamala Harris, became the Democratic Party's nominee but was ultimately defeated by Trump. Messages of support Donald Trump, Biden's political rival and successor, expressed sympathy following the diagnosis. In a post on his Truth Social platform, he wrote, 'Melania and I are saddened to hear about Joe Biden's recent medical diagnosis. We extend our warmest and best wishes to Jill and the family, and we wish Joe a fast and successful recovery.' Kamala Harris also issued a statement, saying, 'Joe is a fighter — and I know he will face this challenge with the same strength, resilience, and optimism that have always defined his life and leadership.' Former President Barack Obama, under whom Biden served as Vice President, paid tribute to his former colleague's determination. 'Nobody has done more to find breakthrough treatments for cancer in all its forms than Joe, and I am certain he will fight this challenge with his trademark resolve and grace. We pray for a fast and full recovery.' Biden's office said further updates would be shared in due course.
